Abstract

Un procédé de conception d'un élément de verre ophtalmique (1) utilise une première surface complexe et continue sur tout l'élément, et une autre surface complexe et continue à l'intérieur de portions juxtaposées (2). Les deux surfaces sont combinées au sein de l'élément de verre ophtalmique. En outre, les portions de ladite autre surface comprennent une bande commune, dans laquelle l'astigmatisme involontaire de ladite autre surface peut être faible. L'élément de verre ophtalmique possède alors un astigmatisme involontaire total qui est réduit, sans procurer de gêne à un porteur de cet élément en vision dynamique.
